Helios and Matheson Analytics Inc (NASDAQ: HMNY) closed up 47 percent Monday on news of an increased stake in MoviePass.

That brings the stock up 330 percent year-to-date — and one expert thinks it’s still has room to run.

“We argue large movie theater chains will benefit from MoviePass that we expect will help revive movie ticket sales, which leads to more concession sales,” Maxim analyst Brian Kinstlinger wrote in a Monday note. “Furthermore, we believe the Hollywood studios may be less hesitant than the theater chains to compensate MoviePass if it can fill more seats.”

MoviePass recently reported that it saw a 30-fold increase in paying monthly subscribers from 20,000 in August to 600,000 in October.
